What is Tempestatistics about?
Tempestatistics is a project by three high-school students from Finland to design, create and test a fully-featured do-it-yourself atmospheric sounding system. We knew this project would be very challenging, but decided to just go for it and see how far we could get.
Starting off we created a prototype design of an insulated and shock-proofed frame with low cost electronic components and sensors inside. Conducting a few small tests indicated that the different components and design solutions would work in atmospheric conditions. It was time to put them all together and ready our DIY radiosonde for the the final test, a real atmospheric sounding.
The test flight was realised with help from the Finnish Meteorological Institute at Jokioinen, Finland on 22nd January 2018. Right after the launch everything seemed to be working fine until the GPS sensor stopped working at 2500 meters. A few minutes later we got no more messages from our radiosonde.
The only thing we could do was to wait. Finally, an hour after the launch, the Tempestatistics radiosonde sent us new information about its landing site. We packed our car and started driving towards the coordinates only to have the sonde and all its sounding data successfully recovered.
